I’m going to a conference this weekend, so I’ve been preplanning all my time slots (double- and triple-booked, of course, as I do). My last conference was DragonCon, and it used a DragonCon-branded mobile app that was built using Core-Apps’ EventLink and FollowMe platforms. It really struggled to keep up with the heft of DragonCon–every load of or task-switch to the app checked the servers for event info and friends’ statuses, I don’t think Twitter postings worked, and the app crashed pretty frequently on my iPhone 4, particularly when network conditions were bad. I really, really hope DragonCon switches to Guidebook this year. The conference this weekend is much smaller…
